2005 Audi A6 Park Brake Probs - Binding/Smoke!

[Zeemax_Mini]

I've got a 2005 Audi A6 which for the past few months has been flashing the "Parking Brake Malfunction" warning, but the brake would always still work fine. This morning, however, I parked up after driving just 2 miles to find the rear drivers side arch billowing smoke and the stench of hot brakes! So I'm assuming the brake is sticking, but I thought the parking brake (electromagnetic thing) only operated on the fronts. Any ideas?! I'm guessing I'll have to take it to Audi to have the codes read etc which is going to get expensive!

Cheers,

Parking brakes work on the rear not the front.

One of the sensors has gone in mine since the ice & snow and shows parking brake malfunction but still works ok.

Mine have done exactly the same - since the ice/snow, the light has been coming on but the system was still working normally, until today! Seems like the parking brake is probably sticking then, any ideas whether its likely to be mechanical (sticky piston etc) or electronics not releasing it?

Cheers!

I am booking mine in to main stealer (under their warranty) so will find out when it's done.

Cheers - I've read that if you unplug the module in the boot the rear park brake will release, so I'm going to try that later and see if it releases the wheel so that i can atleast drive it to a specialist. Sounds like it's going to be expensive though, bloody electronics too clever for their own good!

Well unplugging the module has released the wheel so atleast it's drivable! I guess the next step is to get the fault read and then try to replace the failed part, hopefully something cheaper than the module itself!
